    well guys pretty much I need to turn in an assignment next week that consists of a user inputting a number, and I spell it out for them. for example:

    Please enter a number: 452 (say user inputs 452)

    You entered: Four hundred fifty two.

    my teacher explained to break it down, for example there could be 9 hundreds (one hundred, two hundred, three hundred, etc upto nine hundred)

    same thing goes for tens, and ones.

    This is what I got in my code so far, but I know i'm doing something wrong.
    Code:
    
    int hundreds;
    int tens;
    int ones;
     
     
    scanner input = new scanner (system.in);
     
    s.o.p("please enter a number:");
    hundreds = input.nextInt();
     
    if (1 == hundreds)
      {
         system.out.println("One-Hundred);
     }
     
    else if (2 ==hundreds)
     
      {
         s.o.p.("Two-hundred);
     }
    

    how can i figure out how to to configure whats in the "tens" position. for example, in the number above, the "5" position.

    You'll obviously need some constants defined. There are efficient ways and inefficient ways to define them.

    What constructs (Java data types) do you think you'll need to complete this assignment?

    What other code do you have so far? The above looks like brainstorming code.

    Have you written out, in plain text, the steps you need to take for doing the analysis? This assignment is more of a "how do I solve the problem?" assignment than a "what is the syntax I need to code?" assignment.

    What observations can you make about numbers and how you say them?

    For instance, if a number is only two digits long, you will never need: (multiple choice)

    A. the constant "one"
    B. the constant "hundred"
    C. the constant "thirteen"
    D. the constant "fifty"

    (the above, I'm hoping, you will find quite obvious, but that's the direction you need to be thinking)

    Here's another BIG hint.

    Say these numbers outloud, and recognize what they have in common, and what is different.

    1
    1,001
    1,001,001

    Then, this number

    452,452

    These should give you a big clue about how to structure your code.

    Hi

    I think modulus operator, %, will be very useful in this assignment so you might want to read up on it. For example look at this:-

    Code:
    theNumber = 3393 ;
    thousands = theNumber / 1000 ;
    theNumber = theNumber % 1000 ;
    
    The above code would results with thousands=3 and theNumber=393. You can repeat the process to get the hundreds, tens and ones.

    ok guys i got this so far, but I have no idea how to incorporate the tens and ones.

    Code:
    import java.util.Scanner;     
        public class numtoword
       {
       
           public static void main(String[]args)
          {                     
           
           int hundreds;
           int tens;
           int ones;
           
           Scanner scan = new Scanner(System.in);
           
           System.out.println("Enter number ");
           int x = scan.nextInt();
    
           hundreds = x / 100;
           tens = (x % 100) / 10;
           ones = (x % 100)%10;
    
            if (x==0)
            {
              System.out.println("Zero");
             }
              else if  (x>99 && x<200)
              
              { System.out.println("One Hundred");}
    
               else if (x>=200 && x<300)
               {System.out.println("Two hundred");}
               
               else if (x>=300 && x<400)
               {System.out.println("Three hundred");}
            
               else if (x>=400 && x<500)
               {System.out.println("Four hundred");}
              
               else if (x>=500 && x<600)
               {System.out.println("Five hundred");}
               
                else if (x>=600 && x<700)
               {System.out.println("Six hundred");}
               
                else if (x>=700 && x<800)
               {System.out.println("Seven hundred");}
               
                else if (x>=800 && x<900)
               {System.out.println("Eight hundred");}
               
                else if (x>=900 && x<1000)
               {System.out.println("Nine hundred");}
            
            
          }
       }
    
          
             
     
    like if the user enters : 587 , i got the "FIVE HUNDRED" figured out, but how would I incorporate the 8 and the 7? if anyone can please help i'll appreciate it. The teacher postponed the assignemnt until tommorow because we are all having problems with it. Someone mentioned to use switches, none of us know how to do it.

    I'm assuming your number range is 0 -> 999.

    You have the number in x. You then need to find out how many hundreds, how many tens, and how many ones. It looks like you've done that.

    For your hundreds you will do a few things. First check to make sure it's greater than 0. If it's not then you can skip your hundreds logic. If it is greater than 0 you should be able to print out: "One", "Two", "Three", etc. Now since it is in the hundreds position you can follow it with a standard printing of "hundred". Do not combine them into printing "One Hundred", "Two Hundred". I'll explain why later...

    The tens can be done in the same fashion. Except this time you will want to make sure the number is 2 or higher. Since there is no "tenty" only "twenty", "thirty", "forty", etc...

    For the ones position you can use the same logic you did with the hundreds except you don't tack on "hundred". If you make this a separate function you can use it for both hundreds and ones position. However you also need to see if the tens position is a "1". If it is you need to call a "0" a "ten", call a "1" an "eleven", etc.

    That should take care of all numbers.

    A switch statement looks like this:

    Code:
                    switch (x) {
                        case 1:
                            y = 3;
                            break;
                        case 2:
                            y = 4;
                            break;
                        default:
                            y = -1;
                            break;
                    }
    It's the same as:

    Code:
                    if (x == 1) {
                        y = 3;
                    } else if (x == 2) {
                        y = 4;
                    } else {
                        y = -1;
                    }
    I generally use if statements though since if your logic changes they are usually easier to add to. I haven't found a particular advantage to switch statements for what I've done.

    Looking at your code above you might consider changing:
    Code:
    else if (x>=200 && x<300)
    to:
    Code:
    else if (hundreds == 2)
    Examples of solution, without a solution...

    Code:
    // three lines of your code
    hundreds = x / 100;
    tens = (x % 100) / 10;
    ones = (x % 100)%10;
    
    // something is missing here... exercise for you!
    LowNumberPrint(hundreds, false);
    System.out.println(" Hundred ");
    
    if (tens >= 2) {
      // logic to print twenty, thirty, etc.
      if (ones > 0) {
        LowNumberPrint(ones, false);
      }
    } else if (tens == 1) {
      LowNumberPrint(ones, true);
    } else {
      LowNumberPrint(ones, false);
    }
    Code:
    private static void LowNumberPrint(int iNumToPrint, boolean bIsTeens) {
      if (bIsTeens) {
        // print out teen numbers (10-19)
      } else {
        // print out ones numbers (0-9)
      }
    }
    Hopefully this gives you something to poke at... I didn't throw it into my compiler so hopefully it's close enough to understand. I'm sure somebody will find an error in the code but hey... that's what forums are for! :p

    Of course if you're REALLY on a time crunch you could do....

    Code:
    if (x == 0) {
      System.out.println("Zero");
    } else if (x == 1) {
      System.out.println("One");
    }......... else if (x == 231) {
      System.out.println("Two Hundred Thirty One");
    }......... else if (x == 999) {
      System.out.println("Nine Hundred Ninety Nine");
    }
    
    Although you might want to write a program to write the code for you! :)

    Ok. Back.

    I completed the assignment. After you turn yours in and get a grade, come back and post here with your solution. I'll then also post mine and we can compare techniques.

    I wrote a driver to test mine. Here's the driver so you can test yours before you turn it in. ;)

    Code:
    public class numtoword {
    	public static void main(String[]args) {                     
    		for (int i = 0 ; i < 1000 ; i++) { 
    			numtoword2(i) ; 
    		} 
    	}

    hey todd, i really appreciate your help. I saw what u did, but our teacher specifically said he didnt want 999 different statements. This is what i got so far..it works for all numbers, but doesnt for the teens. like 526, 786, 502, 145 all work fine, but 112, 219, 814, it doesnt work. check it out...

               System.out.print("One Hundred");
               if (x>=200 && x<300)
               System.out.print("Two hundred");

               System.out.print("four hundred");
               if (x>=200 && x<300)
               System.out.print("five hundred");
               if (x>=200 && x<300)
               System.out.print("six hundred");
               if (x>=200 && x<300)
               System.out.print("seven hundred");
               if (x>=200 && x<300)
               System.out.print("eight hundred");
               if (x>=200 && x<300)
               System.out.print("nine hundred");
               }
    
    And, similarly for this switch block, when will CASE 0: through CASE 9: ever hit?

    Code:
                if (tens>=10 && tens<20)
                  switch (tens)
                  {
                     case 0:System.out.print(""); break;
                     case 1: System.out.print("eleven"); break;
                     case 2: System.out.print("twelve"); break;
                     case 3: System.out.print("thirteen"); break;
                     case 4: System.out.print("fourteen"); break;
                     case 5: System.out.print("fifteen"); break;
                     case 6: System.out.print("sixteen"); break;
                     case 7:System.out.print("seventeen"); break;
                     case 8: System.out.print("eighteen"); break;
                     case 9: System.out.print("nineteen"); break;
                     default: System.out.print(""); break;
                  }

    I don't think so.

    I don't think so.

    Look again.

    I had this very problem on a final exam. I wrote code matching what the professor had in mind, while one of my classmates wrote the 1000-case-statement version, putting "..." in the middle rather than including the actual code!

    I got a better grade on the test than my classmate did, even though his code was easier to read, and its correctness was easier to confirm! So what if it wouldn't actually compile and run?

    x can be any number... so I think this is okay. The 2nd part you pointed out is correct though.

    If you look at my posts up above which were just recently added back you might see some more help too.

    x cannot be any value to enter the IF block. Only when (x==0) will the IF block be entered. And then, it will NEVER match any of the nested conditions (which, are pointless anyway).

    You're right. I didn't see the {. I'm used to looking at my own code (I always use {}) and since there weren't any in the other if statements I didn't notice it in the first one. Good catch!
